(usagi-users 03620) Problem disabling autoconf

	Hello,

I can't seem to write to /proc/sys/net/ipv6/<iface>/accept_ra (or 
autoconf) before a <iface> has an IPv6 address... but if I write to 
said file after kernel creates it, autoconf is attempted by the kernel 
first :(

What is the correct way to safely disable autoconfiguration on a single 
(not all) interface (already existing but not yet brought up)?

Thanks in advance,
